ADJUSTABLE MIRROR-HOLDER.

rors which are used 1n connection with dressing-cases or other furniture will be retained I at any desired point of adjustment; and it pertains more especially, first, to the construction of a circular bearing-plate; second, to the device for adjustably supporting a slidable friction-brake at a central point '20 within the circle described by said bearingplate, and, third, to the device for adjustably connecting the mirror-frame with the brake mechanism in such a manner that they will cooperate perfectly regardless of the fact that they are not always attached to the mirrorframe and frame supporting standards in exactly the same relative position to each other.

My invention is explained by reference to 3 the accompanying drawings, in Which Figure 1 represents a front view thereof attached to one side of a mirror-frame andv frame-supporting standard. Fig. 2 re resents a side view of the device shown in ig.

1. Fig. 3 represents a transverse section of the device, drawn online m a; of Fig. 1. Fig.

4 represents a side view. Fig. 5 represents a transverse section of a modified form of the device with pivotal connection of the brake I mechanism omitted. Fig. 6 and Fig. 7 rep-- resent similar views to those shown in Figs. 1 and 2 with the semicircular bracket attached to mirror-frame and the brake-actuating arm attached to the stationary mirror-supporting standard. Fig. 8 represents a front view of the device with a bifurcated brake-actuating arm.

Like parts are identified b the same reference characters throughout t e several views. 1 represents a mirror, 2 the mirrorsup- 7 porting frame, and 3 the frame-supporting standard. The frame 2 is pivotally supported from the standards 3 at its respective sides upon pivots 4. 5 5 r 6 is a circular plate, which is permanently Specification of Letters Patent.

connected with one of the standards 3 by the screws 5 5. v j 7 is a friction hearing or brake, which is retained in contact with the convex surface 8 of the plate 6 by a radial arm 9. The radial arm 9 is pivotally connected with the horizontal base 10 of the plate 6 by the pivotal pin 12 and pin-retaining lugs 13, said pin 12 being located at the central point within the circle described by said circular late 6, 6 whereby the brake-bearing 7, whic is adjustably supported at the outer end of the radial arm 9, is caused to describe a circle around the periphery of said plate. The bearing or brake 7 is adjustably supported upon said radial arm 9 and against the periphery of said late 6 by a hand-nut 14, which hand-nut as screw-threaded hearings on said radial arm. It will be obvious that.

by this arrangement the friction of the brake- 7 5 bearing 7 may be increased or diminished as I the weight of the mirror may require by turning down the hand-nut 14 on the screwthreaded bearing of the arm '9. While the brake-bearing 7 is preferabl made of metal and provided with a yielding cushion 16, formed of felt, leather, or other similar material, said brake may, if desired, be formed of metal alone or other hard substance and the cushion 16 dispensed with. Motion is communicated to the brake mechanism from the oscillating or pivotally-supported mirror through the brake-actuating bracket 17, which bracket is rigidly fixed to the surface of the mirror-supporting frame 2 by screws 18-. The free or outer end of the bracket 17 has loosely-fitting bearings in the slot 19 ofv the radial arm 9, which permits of the change in the relative adjustment of such parts to each other. For example, in case the mir- 5. ror-supporting frame is of greater .or less thickness the bracket 17 will be farther from or nearer to the pivotal support of said radial arm, so case the standard 3 is of greater or less thickness the relative adjustment of said radial arm 9 and bracket 17 will bein like manner changed to each other without materially affecting their 006 eration with each other. It will of course e obvious that the circular bearing-plate 6, together with the brake and brakesupporting radial arm, may, if desired, be attached to the mirror-supporting frame and the bracket 17 attached to the frame-supporting standard, or, in other words, the relative position of such parts be :10

as I

changed, as shown in Figs. 6, 7 and 8, without chan ing the 0 eration of the device or without eparting om the essence or spirit of my invention It will also be obvious that, if desired, said brake mechanism may be located upon the rear of the mirror and mirror-supporting standard instead of in front, as lndicated in Fig. 7. It will be further understood that while I have shown and described the free end of the bracket 17 operating in a slot formed in the radial arms 9 the end of said bracketmay be bifurcated, as

' shown in Fig. 8, in which case a fork of said bracket will be brought upon each ide of said radial arm,'and the slot 19 may be dispensed with. y

In the modified form shown in Figs. 4 and 5 the radial arm 19 is supported entirely from the semicircular plate 6 and the central ivotal connection 12 is dispensed with.

en the pivotal connection is dispensed with, I provide the radial arm 19' with an interior bearing-plate 20 in addition to the ext'erior bearing-plate 7 when the cushion 16 may be inserted between the bearing-plate. 20 and the concave surface of the semicircular plate 6. I

To provide for fastening the circular bearing-plate 6 and the arm 17 t0 convex surfaces, I preferably form the bases 10 and 10 of such arts with concave surfaces 12, as shown in ig. 3, whereby they are adapted to be readily fitted to furniture having either fiat or convex surfaces, as circumstances may require. The semrclrcularplate '6, is provided I with alongitudinal slot 6 for the reception of 2. The combination of a semicircular bearing-plate, a radial arm pivotally connected at a central point within said bearing-plate, a frictional bearing adjustably secured to said radial arm and bearin -plate, an actuatingarm slidably connecte with said radial arm and means for connecting said parts with a pivotally-supported mirror and a mirror-supporting standard.

3. The combination of a semicircular bearing-plate, a radial arm pivotally connected at a central point within said bearing-plate; a frictional bearin 'adjustably secured to said radial arm and caring-plate, an actuatingarm adapted to be connected with said radial arm at various points of adjustment both laterally and radially and means for connecting said parts with a pivotally-supported mirror and a mirror-supporting standard.

4'. The combination of a semicircular bearing-plate, a radial arm pivotally connected at a central point within said semicircular bearing-plate provided with a longitudinal slot for the reception of the free end of an actuating-arm, a frictional bearing adjustably secured to said radial arm and bearing-plate,

' an actuating-arm slidably connected with said radial arm and means for connecting said parts with a pivotally-s11 ported mirror and a mirror-supporting stan ard. 7*

5. The combination of a semicircular bearing-plate. provided with a longitudinal slot for the reception of a radial arm, a radial arm operating in said slot pivotally connected at a central point within said semicircular bearing-plate, a contact-bearing adjustably secured to said radial arm; and bearing-plate, an actuating-arm slidably connected with said radial arm and means for connecting said parts respectively with a pivotally-suppocilted mirror and a mirror-supporting standar y In testimony whereof I affix my signature in the presence of two witnesses.
